273, This is for you. I know from your posts that you are quite knowledgeable. Not wasting time with Turk, he doesn't know how an air bleed works. You are confusing force with pressure [ loading ]. Look at the formula in post #112. Pressure= force divided by area [ not multiplied ]. In...

RRR, Post #113, you disappoint me; I thought you were smarter than that. Look at the formula in post #112: Pressure= force divided by area. The force is the force of the expanding gas. The area is the piston area. If the area gets bigger [ a bigger diameter piston ], then the pressure gets...

Maybe this will do it. Force per unit area. The coin sinks into the plasticine further when pushed end-on because it has more pressure with less the area. Get it now Turk or are you too dumb???? Get it now 273???

273, Post 106. Nope wrong again. Confusing weight with pressure. As I said earlier, if big piston areas were able to perform your magical idea, it would be reallllllllllllly easy to make reallllllllly big HP........& we would see lots of engines with huge pistons. But we are not...

...it's greater area. I do not know how many examples are needed until the message sinks in. So I will try some humour.... There is a lump of dog s**t on your patio. You get the garden hose to get rid of it. You adjust the hose nozzle for a concentrated stream...& blast away the mess. Had...

Boring adds power.... just like stroke does...... because more air is ingested into the engine to increase the unit loading on the crank via the bore & stroke.

Turk, I will answer your question first. Post #98. Both engines will make the SAME POWER. That is because both pistons have the same total force applied [ 100 lbs ] ; what will be different is the lbs per square inch. The respective areas of a 4 & 5 inch piston are 12.6 & 19.6 sq in. The...

Some engines require 50* to idle properly [ see below ]. My engine idles with 48* @ 800 in gear & has a smooth idle with a big cam. Unless you know how to do this electronically, using an adj vac adv connected to manifold vac is the way to have a lot of idle timing........& have the timing drop...

When it fails to start, remove a plug lead & lay the lead on the valve cover, screwdriver inside; create a 3/16" to 1/4" air gap. Crank & watch for white/blue spark. No spark: obvious; yellow spark = weak spark.

Touche...

I would ditch those little filters in the seats. Just use one main external filter.

Go to the Penrite.com. website & look for the description of 'Friction Modified' oil. FM oils are 'thinner' to give better economy. Penrite make oils that are NOT FM'ed, which is what I use in my engines & engines that I build. Not saying that the above is the reason for the oil pressure loss [...

65. Would love to see the TSB. know where I can read it.

273, If your BS was correct, everybody would be building engines with 7" pistons & 2"stroke. Oh, the free hp because of the large piston area!!!! The rubbish you posted in post #78, you posted a few weeks back. I thought I will let it go. But then you repeated it.... One more try for...

How much voltage the body gets zapped with is based on exactly the same principle as the voltage reqd to bridge the air in the spark plug gap. Rarely would the voltage rise to the rated voltage of the coil. Could be a 50kv coil but it only uses 18kv to fire the plug gap. Same with the human...

No, I have just proved you are wrong [ you asked for proof, remember... ] but you don't 'get' it..... And the above example has nothing to do with energy being created or destroyed. Energy can, & does, get converted to different forms of energy, which is exactly what is going on here...

Proof? First one is common sense. Like I said, if a big piston had more force on it, nobody would use...or design..... an engine that had smaller bore/longer stroke. Particularly where efficiency & economy are important such as commercial vehicle engines....which use long stroke engines. At...

The reason for a LOT of initial [ idle ] timing is the same reason you want to start the centri curve early. The big[ger] cam produces a less dense mixture at lower rpms, which means more ign advance is reqd.

Those are early #s, so if it is 318 it is probably a Poly 318 block.

If you want the best [ most spark energy, 0.060" plug gaps ] from the HEI module, use a 0.4 - 0.6 ohm E core coil, such as MSD #8207 or similar. Just because you are using the GM module with a canister coil does NOT mean the bal res can be omitted. Most canister coils that are used with...

...3.75"stroke. Both have the same stroke but the Chev has a shorter rod. This means that the Chev piston is higher in the bore when the rod is at 90* to the crank throw where it gets maximum mechanical advantage. Since it is higher in the bore, it is seeing greater force from the expanding gas...

If you have a hard pedal [ engine off ] & the pedal goes to the floor [ engine running ], you have air in the system.

Closed chamber heads will only be a benefit [ over open chamber ] if the piston crown comes to within 0.060" [ or less, which is better ] of the head.

The biggest mistake enthusiasts make is using a colder plug...when they should be going one step hotter.

Five degrees 'off'. Off which way, advanced or retarded? I am always amazed at the time spent tinkering to get the cam exactly at some amount of adv or ret......for a cam that has not been used or tested & therefore no info where the best position [ position: whether it should be advanced or...

Roller lifters are taller than stock FT lifters, so p'rods will be shorter.

Yeah, the small carb was faster over the quarter than the Dom....That is because the engine has to get to 4000 rpm before it can get to 6000 rpm where the engine might use the extra flow of the Dom...

3.91s are like 4.11s.....a PITA!!!!

The 8:1 CR, 120 psi cranking pressure, is why it wants a lot of timing at idle. To get the optimum idle timing [ let us ay 25* ], you have a couple of choices: - shorten the curve in the dist to about 11-13*. That will give 36-38* at WOT. The low comp ratio will want more timing. This much...
